"It was a complex project. They were very careful with their procedures and raised sunken concrete sections next to the house and around a pool to allow for drainage. They filled the major cracks. They were courteous and on-time over several days. After many years the water in the basement problem has been resolved."

Basement Waterproofing questions, answered by experts

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.
